NON-BEFILLABLE BOTTLE.

Application filed January 26, 1912.

' Specification of Letters Patent.

Patented Dec. 3, 1912.

Serial No. 673,670.

To all whom it may concern Be it known that I, VVILHELM Brrrwncnn, asubject of the German Emperor, residing at Eberbach, Grand Duchy ofBaden, Germany, have invented certain new and useful Improvements in orRelating to Non-Refillable Bottles, of which the following is aspecification.

My invention relates to a bottle closing device in which two separatebottle necks are provided, one of which is used for filling, and afterfilling is closed by a stopper put in, while the other one is used fordischarging the bottle, and is provided with a closing body which makesit impossible to refill the bottle.

A structural embodiment of my invention is illustrated in theaccompanying drawings, in which- Figure 1 is a longitudinal sectionalview showing the filling neck open. Fig. 2 is a similar View showingsaid neck closed. Fig. 3 is a cross-section on line AB of Fig. 1. Fig. 1is a vertical section and a plan view form of protective body which maybe inserted in the discharging neck.

The bottle is provided with two adjoining necks a and b which have acommon inner wall, but otherwise are entirely independent of each other,these necks being arranged in parallel relation and having the sameheight. They communicate with the body portion of the bottle at the topthereof, but they are devoid of communication with each other. The necka corresponds to the ordinary bottle neck and is used for emptying thebottle. Its bottom portion 0 is tapere and contains a tapering valve dweighted at the bottom which, owing to its weight, engages with thetapering portion 0 of the bottle neck and thus prevents the liquid frombeing introduced into the bottle. If the bottle is tilted the valveslides back and thus uncovers the opening in the bottle neck, so thatthe liquid introduced can escape. Its mobility is limited by a reducedportion 6 arrange in the bottle neck.

In order to prevent the valve (Z from being raised from the outside, forinstance by the introduction of wires or the like, there is insertedabove the same a protective device or guard 9! provided with overlappingribbed surfaces which also consist of glass, and after the introductionit is sealed or otherwise permanently secured in the bottle neck.Instead of transverse ribs, the protective body could also be providedwith perforations h as shown in Fig. l. The spaces between the ribs f inthe first form ofguard, and the perforations h in the second form,constitute fluid outlet passages as will be understood. 7

For filling the bottle, the second neck I) which opens directly into thebottle is used, and after the filling is finished, it is closed by aground-in glass stopper Z. The latter has such dimensions that its outerfront surface either is flush with the bottle neck or is countersunktherein, so that it cannot be seized from the outside, and as theseizing with the hand or with mechanical means is impossible, itprovides a permanent clos-- ing, so that an opening of the bottle neckcan be effected only by breaking.

While the bottle structure, as above described, is incapable of beingfraudulently refilled; that is to say, of being refilled for fraudulentpurposes by the purchaser of the filled bottle; it is obvious that foreconomic reasons the bottle should be capable of being refilled by theoriginal bottlers of the liquid. This is only possible by breaking awaythe filling neck from the discharge neck, after which the bottle may berefilled and a new neck fused to the body of the bottle and thedischarge neck. After this the glass stopper may be ground in the newfilling neck so as to permanently seal the same.

The bottle can of course be made of any desired material such as forinstance sheet metal, porcelain, pottery, etc.

What I claim is:

1. A non-refillable bottle provided with adjoining filling anddischarging necks having a common inner wall, both of which neckscommunicate with the body portion of the bottle; a valve arranged in thedischarging neck and normally closing communication between that neckand said body; a guard permanently secured in said discharging neckabove said valve for preventing access to the latter, said guard beingprovided with fluid outlet. passages; and a stopiper permanently securedin the filling nec 2. A non-refillable bottle provided with adjoiningparallel filling and discharging necks, of the same height, both ofwhich communicate with the body portion of the bottle at the topthereof, but are devoid of communication with each other ;v a valve arvalve for preventing access to the latter, said guard being providedwith fluid outlet passages; and a stopper permanently secured in thefilling neck.

In testimony whereof I have hereunto set my hand inv presence of twosubscribing 1 witnesses.
